However, having signals with varying features, such time-frequency decompositions are very restrictive. A more flexible and adaptive sampling of the time-frequency plane is achieved by the nonstationary Gabor transform. Here, the resolution can evolve over time or frequency, respectively, by using different windows for the different sampling positions in the time or frequency domain (Multiwindow-frames). This adaptivity in the time-frequency plane leads to a sparser signal representation. In terms of audio inpainting, i.e., filling in blanks of a depleted audio signal, sparsity in some representation space profoundly influences the quality of the reconstructed signal. We will compare this quality using different nonstationary Gabor transforms and the regular Gabor transform with different types of audio signals.}, subject = {Mathematik}, language = {en} } @incollection{Lantzberg2013, author = {Lantzberg, Daniel}, title = {Rank-M Frame Multipliers and Optimality Criterions for Density Operators of Rank M}, series = {Current Trends in Aanalysis and Its Applications}, volume = {2015}, booktitle = {Current Trends in Aanalysis and Its Applications}, publisher = {Springer}, isbn = {978-3-319-12576-3}, doi = {10.1007/978-3-319-12577-0_76}, pages = {695 -- 704}, year = {2013}, abstract = {Ever since the introduction of frames in 1952 [4], the connection between frame theory and decompositions of certain operators, particularly the identity operator, into rank-ones began to be elaborated. Abandoning the idea of restricting to tight frame-like expansions, with respect to systems arising from a single template function, one is led to the concept of resolutions of the identity, with respect to more general systems than the usual rank-one expansions of the identity. In this study, we will investigate various notions of possible generalizations of optimality criterions for rank-M frames and corresponding multipliers. Explicitly, we will lay stress on continuous M-frames, arising from irreducible group representations of locally compact groups, have a look at its connection to time-frequency analysis and comment on adequate notions of optimality.}, subject = {Mathematik}, language = {en} } @inproceedings{AbkeGoldRoznawskietal.2013, author = {Abke, J{\"o}rg and Gold, Carolin and Roznawski, Nina and Schwirtlich, Vincent and Sedelmaier, Yvonne}, title = {A New Approach to Collaborative Learning in Software Engineering Focussed on Embedded Systems}, series = {2013 International Conference on Interactive Collaborative Learning (ICL)}, booktitle = {2013 International Conference on Interactive Collaborative Learning (ICL)}, publisher = {IEEE}, isbn = {978-1-4799-0152-4}, doi = {10.1109/ICL.2013.6644663}, pages = {610 -- 616}, year = {2013}, abstract = {Software Engineering is a very complex and abstract process and therefore hard to learn and hard to teach. Especially in mechatronics software engineering is not the main focus of the university studies. Therefore students have little understanding and low motivation to spend time on it. In this paper, we share some experiences on how we tried to give students a deeper understanding for software engineering, its processes and the complexity of software engineering projects. To that end, we chose a new didactical approach consisting of direct instruction and activating learning styles in parallel. The classical lectures were supplemented by a seminar and a project phase to allow students to apply their theoretical learned knowledge without delay in realistic settings. We combined active and passive learning styles to give students the opportunity to consolidate factual knowledge, foster soft skills (e.g. presentation and communication skills), improve team work and gain a deeper understanding of software engineering processes. The experiences of our courses in summer semesters 2010 and 2012 lead to a further development of our didactical approach in 2013. As a consequence, we tried further methods to spread needed information across the student working groups by using a wiki-system, a market of knowledge or mixing the groups between seminar and project phase. At the end of the seminar phase quality gates were implemented and also awards at the end of the project phase. Systematically evaluations at the end of the seminar phase and at the end of the project work show the learning outcomes and possible further improvements of our didactical approach.}, subject =
